' description, reference being hadto the accompanying drawings, formingpart of this speciiication. i

This invention relates to what is ordinarily I known as a self-actingspinning-mule.

I haveillustrated 'my'inventio'n in conj unction with sufticientportionsof the well-known Mason mule to readily enable any one skilledin this class of spinning machinery to-fully understand the cooperationof my improvements and the objects thereof. v

' The operations of the spinning-mule comprise three sets of motions, asfollowsi first, running out the catriagaturning the drawrollers, androtating thesspindles for spinning the yarn; second, backing OH orunwinding the yarn from the spindle-heads to the cops and depressing thefront fuller; third, running in the carriageand windingon the previouslydrawnaud twisted yarn. The dofting of the cops from the spindlesisusually performed while the carriage is at the outward limit of itstravel, or after the carriage has been run in a little distance. v Thistime is selected be-.

cause the front faller has then depressed the yarn toward-the base ofthecop, so that after dotting the broken end of yarn can be secured tothe spindle at a point where the base of the next-formed cop is tobegin; In doffing it'is customary, after the machine has stopped, to

manipulate the machine by. hand in order to.

turn the spindles forward and backward'to wind on a little by hand andto gain sufficient slack to tie the yarn ends to the spindles, andmoving Lethe machine by hand in order" to slightlyoperate the spindleshas become such" a necessity thatin doffing oneor two operators arerequired to pull upon the driving-belt to effect the desired result onthe spindles. During the period of the operation of the wind-0n motionand the simultaneous running-in motion in the form of mule wherein a topsliding rack'having but two motions is used as a Serial No. 229,853. (Nomodel.)

clutch open, an adjustable stop-arm fixed on justable block for thespring to takeagainst. Injorder that my invention may be fully the bestformof my invention so far devised I by me, which form may be variouslymodi;

chine-frame, back-oft" arm, and section-rod being broken off and theback-oil wheel being in broken lines. Fig. 2 represents a top plan viewof the parts shown in Fig. 1. Fig. 3 represents an enlarged detachedview of portions of the back-oil rod and the wind-clutch lever, togetherwith my spring-acted wind-clutch dog and adjustable block for thespring. Fig. 4 represents a side elevation of a Mason mulehead having myimprovement attached thereto.

In the said drawings like numbers of reference designate correspondingparts throughout.

Referring to the drawings, the number 8 designates the machine framingof the mulehead for supporting the various mechanisms situated therein.The sector rod 9 is connected to the sector 32, which is actuated by theconnecting-rod 33 in the usual manner,and the sector-rod rocks thesector 32 and back-off rocker 10, which is pivoted to the frame, and tothe lower end of which the back-off rod 11 is loosely attached, whilethe other end of the hack'olf rod is pivoted to the lower end of theback-off arm 12, (shown partly in full and broken lines,) and whichis-loosel y mounted on the wind-shaft 13, journaled across the ma-.chine-frame. j

Upon the wind'shaft is keyed the backbfi' gear 14, (shown in brokenlines,) and the windclutch 15 is also mounted .on the shaft 13, andconsists of the wind-clutch pinion 17,which is not fixed to the shaft,and the part 16, which is secured by a longitudinal feather on theshaft, and which is adapted to slide on the shaft and to always turntherewith. When the wind-clutch is open, the pinion 17 runs idle orloose,and when the clutch is closed the pinion obviously runs fast withthe windshaft. 1 1

The immediate connections, which lie intermediate of the back-off rod 11for operating the wind-clutch to clutch and unclutch, consist in awind-clutch spring-fork, 18, which is fixed to the stand 19, which issecured upon the ma chine-frame and supports the rock-shaft 20, to oneend of which is keyed the clutch-arm 21 for bearing upon the back of thespring-fork 18, which tends normally to keep the windclntch open, asshown. To the base of the rockshaft is made fast the wind-clutch lever22. WVhen the lever 22 is moved toward the left, the rock-shaft will berocked and will cause the clutcharm to bear upon the clutch-fork, andthereby close the clutch, which, upon the releasing of the lever, willbe opened by virtue of the spring tension of the spring-fork. In the oldform of machine the moving of the wind-clutch lever to close thewind-clutch is effected by means of an adjustable wind-clutch dogmounted on the back-off rod 11, and which is made fast thereon whenacting. The top sliding rack, 23, is shown in portion and liesconstantly in mesh with the wind-pinion 17.

The above'described parts are old and their respective functions arewell known, and the following description will be easily understood.

The drawings show the several parts of the machine in a position whilethe back-ofl' motion is being performed by virtue of the sectorrod9'being moved inwardly indirectly by the connecting-rod 33, therebyrocking the backofi' rocker 10 and drawing outwardly the backoff rod 11,which serves to throw down the up per end of the back-ofl arm 12,provided with a pawl, (not shown,) which pawl takes into the teeth ofthe back-off gear 14 only during thisdownward motion of the back-off armand acts to turn the back-off gear throughout the downward movement ofsaid arm. The motion is transmitted from the back-off gear 14 to thespindles by means of an idle-gear, 34, meshing with a gear fixed uponthe frictionclutch shaft 35, and as the, friction-clutch 36 carries thespindle band or rope and is closed during the back-off the spindles arebacked oil" or reversed through these means. At the completion of theback-oif the wind-clutch dog 27, fixed on the back-off rod 11, is soadjusted as to push upon the wind-clutch lever 22, and therebyindirectly close the wind-clutch 15. At this time the lower rack is runinwardly, and as this moves the top rack in, the pinion 17 being nowfast relative to the wind-shaft and the connected back-oil gear, thismovement of the top rack obviously rotates the spindles through theintermediate apparatus before alluded to, and winds on the yarn whichhas been previously drawn and spun.

As beforestated, the doffing of the cops is usuallyperformed when thecarriage has moved in slightly from the outward limit of traverse, andunder this condition of the carriage the wind-clutch is necessarilyclosed and the entire apparatus between the spindles and the running-inpulley is all connected when the machine is stopped for dotting, so thatto turn the spindles slightly by hand all of the aforesaid apparatusmust be moved, and this I deem a great defect.

It is the chief object of myinvention to overcome this defect by holdingthe wind-clutch open during dofling, thereby disconnecting the apparatusat this point. This resultI accomplish by means of using a stop whichmay be moved in or out of engagement with the immediate connections foroperating the windclutch, which, when the stop is interposed, isprevented from closing. I have here shown the stop as being used toaffect directly the operation of the rook-shaft 20. The stop itselfconsists of amovable member, 24, pivoted to the machine-frame andadapted to be thrown into engagement with the adjustable stop-arm 25,which is mounted on the rock-shaft and turns therewith, and is providedwith a set-- screw, 26, for holding the stop-arm in adjusted position.The stop 24 is provided at the pivoted end with the spaced lugs 30,which act in conjunction with the fixed pin 31 on the machine-frame tolimit the throw of the stop in an evident manner. Just before themachine is stopped for doffingI throw the stop 24 over' into thedotted-line position of Fig. 1, so as to lie in the path of the stop-arm25 when the 5' wind-clutchlever is moved by thebaek-off,

rod to close thewind-clutch and obviously stop the rock-shaft and theconnected clutch arm from moving sufficiently to close the windclutch,therebyleavi'n g it unclutched andhold- :0 ing it so while dofling, sothat when the spindles have to be turned by hand only the apparatusbetween thesame and the spindleband, and also the closedfriction-"clutch, its shaft and gear, and the idle-gear and back-offgear and the windshafthave to' be moved,

thus avoiding the labor of moving all the heavier apparatus intermediateof the wind-shaft and'the running-inpulley before referred to.

The employment of the character of'stop-I 2c show for holding thewind-clutch open requires a yielding mechanism to be used at a placenear by in order to prevent breaking or'rupturing the machineryimmediately connected with thewind-clutch, This need I supply by the useof a yielding wind-clutch dog, 27, sliding on the back-off rod 11, inplace of the heretofore rigid dog. This sliding dog is'free on therod,and is engaged by a spiral spring, 28, coiled about the rod and abuttingagainst the adjustable block 29,..which is designed to be adjusted inorder to regulate the time when the compression of the spring will besufficient to push the wind-clutch lever to close the windclutch in theordinary manner while the cops are-being built. It is evident that whenthe stop 24 is putin. play for dofiing the backoff rod will operate, asusual, to push the dog against the wind-clutch lever and close theclutch; but the, stop will hold the lever rig- 4o idly 'and the spring28 will be compressed to compensate for the stoppage of the dog, and

thus prevent the lever or other adjacent parts from being broken. c

It is to be observed that my yielding wind- I clutch dog willperform therequisite function i of closing the wind-clutch while the machine isrunning and forming the cops, and is adjustable by virtue of its springand block to regulate precisely the time for closing the wind-clutch forthe wind-on. My invention permits of the yarn being easily wound uponthe cops by hand to the required extent in dotting, and thisis animportant advantage, since thereby the likely destruction of the cop- 55' nose is renderedless'liable than heretofore.

. I desire to be understood as not being con; fined to the exactconstruction I have here shown of my invention, since there are manyways in which astop can be arranged to co- 6c operate with the immediateconnections for operating the wind-clutch for the purpose of preventingthe closing of the wind-clutch, as

described.

Having thus'described my inv ention;I claim I as new and desire tosecure by Letters Patent- 1. In a spinning-mule, the combination, as
